Don't change how you act, change how you REact. When someone bothers you, think from all points of view and see their intent. Learning to not feel when you don't want to is good. I did. Somehow. It leaves me with something like guilt and calm, but it feels better. Weird but better than frustration and stuff. Then, post calmly after thinking how they'll react.
That's how I dealt with the Ravencroft drama. I didn't feel anything while thinking about it and when it was over I felt good as everyone said how bad they felt.
